David Marsh presented to the East of England branch in April 2003 on the core functions and benefits of a PSO. David defined the PSO as the ''function charged with providing the organisation with the necessary supporting infrastructure and services to ensure that its portfolio of programmes and projects are being effectively and efficiently directed, managed and delivered.''
A PSO can be one of six types: Programme office, programme management office, programme support office, project office, project management office or project support office.
In his presentation David looked in detail at the six types of PSO, the five different support roles and what should the PSO do. He also covered the costs and benefits and PSO terms of reference.
In the second part of the seminar David talked about the foundation and practitioner qualification: The ISEB Certificates in Programme and Project Support Office.
